10" are overkill. A 30Hz note takes 32 FEET to develope one complete cycle. That's why it's louder (low freq-wise) outside some vehicles than inside. Inside you feel the air pressure change, you don't hear the notes. If you want to feel the sound, more cone area=lower possible notes=more air movement=thump in the chest. If you want to hear the sound, smaller cone that rolls off at about 40Hz works better=8". Also, buy or make the correct enclosure for it, makes a world of difference.
For what it's worth, I spent 23 years making a living at installing car stereo. Just my $.02.
Some days will stay a thousand years, some pass like the flash of a spark.
